An 8-alarm fire broke out in Union City last night, burning through six Bergenline Avenue buildings between 21st and 22nd streets.

The North Hudson Regional Fire and Rescue battled the flames for almost 12 hours and was assisted by fire departments of neighboring towns including Bayonne, Harrison, Kearny, and Jersey City.

During the course of the night 13 firefighters were injured, mostly due to slips and falls from the icy street conditions.

Around 40 residents, who were evacuated when the fire reached its third alarm, are currently seeking shelter at the Jose Marti School on Summit Avenue and 18th Street in Union City.

One person, however, remains unaccounted for. However, due to the roofs that collapsed during the fire, officials say it is too dangerous to send anyone inside.
